WiFi App interference?

---

Is it possible for an App to interfere with the WiFi connection? I've downloaded plenty of third party, torrented apps and I've been noticing that my WiFi will work for a few pages and then stop loading, throwing up an error saying "Web page not available" showing the little Android. This would cause me to disable WiFi and go strictly with 3G. Enabling WiFi later would help with a few more pages until it wanted to die again.

After I uninstalled ALL of my apps and unrooted the phone, I've noticed that the WiFi works again (so far at least). I still have the same 1 bar signal from across the house, but it isn't giving any more errors.

I constantly used task killer to free up memory, so I don't think those apps would have made a difference in the sense that they may have been taking up some bandwidth or the such.

Any clues guys? Thanks for any help.

I have the same problem. I rooted and did the settings.db. My wifi will turn on and connect but 20-30 seconds later it just turns off on its own. I haven't unrooted it to see if it fixes it though.

How did you unroot yours?

Thanks

Like, I'm pretty sure that's just karma, dude. Harsh vibes from people like me that make software for a living reaching out and disrupting your chakra centers. And your WiFis.

That and using Task Killer in the first place. Not needed, causes more problems than it solves (and it solves almost nothing on Galaxy S).

I am in the same boat--just started noticing it today when I got home from work and turned the phone back on only to see I wasn't connected to wifi. When I connected to my network again I noticed the 3G icon stayed on the screen with the wifi connection symbol, where the wifi icon used to replace the 3g icon. After a little while, it was gone.

I have rooted and removed some of the AT&T apps but nothing else. I havent sideloaded any apps either. It usually take me a couple of tries to connect to my router (WRT54GL). Sometimes it also seems that my phone turns off wifi by itself.

I hope this isn't a symptom of the battery cover antenna. Does your WiFi signal show as weak in the strength readout?

It does actually turn off wifi by itself! I did the following last night and haven't seen an issue since. As a new user, I can't post links: androidforums.com/samsung-captivate/130163-wifi-connection-turns-off-when-sleep-mode-default.html

From androidforums.com:
By default the wi-fi setting is set to go to sleep (and use cellular data instead) when the screen is off, which will most likely happen while you are streaming music as well as other things. To change it so the wi-fi never turns off, go into the phone's menu -> wireless and network -> wi-fi settings -> tap the menu button and select advanced which has an option for wi-fi sleep policy that had been defaulted to sleep "when screen turns off". There you have the option to change it to "never" or "never when plugged in".

Did a little more playing around with it, finally had to reset my router to maintain any type of consistent connection after restarting the phone. One weird thing is that my old iPhone wasn't able to connect to the router consistently last night until the reset either--it has never had any issues in the past.

After the reset, the captivate did maintain a consistent connection--I browsed a few websites and streamed part of a show from my computer using Allshare.

This morning when I turned on the phone wifi wasn't connected so I went into the settings and looks like the phone had attempted to connect unsuccessfully. I clicked it again to connect and it connected without any issue and was fine until I left for work. The whole thing seems a little wonky, as well as it should automatically try to re-connect if it fails the first time if network is in range, or at least give you an alert.

I just set up tdogz suggestion above, so we will see if it helps.

Haha sorry bud, but after browsing for some good videos to put on the phone my curiosity made me type in "android" in the torrent search box. I was amazed I could do such things.

Before I unrooted the WiFi wouldn't work with full or low bars, not sure of the strength readout.

Running into the same issue, I am positive it is a software issue. It only seemed to happen after I flashed my phone with the Odin One click downloader. Dunno if it is coincidence or not. Going to try clearing the user data from the recovery window to see if it helps. I also notices on the power widget, i cant control GPS from there, blue tooth as well i think.

Yeah, user data reset did not do it. Reflashing now.
